Patented Jan. 16, 12362 3,016,949 FUEL BURNER John Rahhitt, 214 E. 126thSt. New York, N.Y. Filed Aug. 24, 1956, Ser. No. 606,071 2 Claims. (ill.158-104) This invention comprises novel and useful heating device andmore particularly relates to an apparatus for producing a multipliedheating effect from a plurality of burner units or heating elements.

The primary object of this invention is to provide a device forproducing a more concentrated heating effect by an improved associationof a plurality of burner or heater elements.

A further object of the invention is to provide a heating device inaccordance with the foregoing object whereby a pair of burner or heaterelements may be disposed in opposed relation to each other whereby toproduce a reinforced or augmented heating effect.

Yet another object of the invention is to provide a heating deviceincorporating therein a pair of gas burner ele-- ments disposed inspaced parallel relation and whereby burner nozzles on adjacent opposedfaces of the elements may be disposed in vertical relation for producinga reinforcing effect upon the heat from each unit.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

FIGURE 1 is a perspective view showing a suitable form of apparatusincorporating therein the principle-s of this invention;

FIGURE 2 is a vertical transverse sectional detail view taken upon anenlarged scale substantially upon the plane indicated by section line 22of FIGURE 1; and

FIGURE 3 is a fragmentary view similar to FIGURE 2 but showing amodified construction in accordance with the invention.

Referring first to FIGURES 1 and 2, it will be seen that the heatingdevice therein consists of upper and lower wedge shaped heating elements12 and 14 respectively which in the form illustrated are spacedvertically from each other, being rigidly connected together by means ofsuitable supports 16. Supporting legs 18 may be provided whereby theassembly shall be supported in any desired manner. Upon the adjacentfaces of heating elements 12 and 14 there are provided burner nozzles 20and 22 respectively which project toward each other. A combustible fluidmedium such as gas, oil or any other medium is supplied to any suitablesource of supply as by a pipe 24 under the control of a manual controlvalve 26, by means of an air atfixing nozzle 28 to the conduit 30 whichby branch conduits 32 and 34 discharges into the upper and lower rings12 and 14.

In the arrangement illustrated the combustible fuel flowing through theupper and lower rings is discharged from the nozzles 20 and 22 instreams which are directed towards each other as will be apparent fromFIGURE 2. Thus, the spray of combustible from the nozzles of the element20 impinge upon the spray of combustible from the nozzles 22 of theelement 14. These impinging sprays cause a resultant flow of combustiblemixture, a part of which will fiow into the space within the ring, whilethe remainder will flow outwardly to the space surrounding the ring.

The combustion of this mixture will produce a flame and develop heat ina ring-like conformation both within and outside of the verticallyaligned rings thereby pr ducing a more intense heating effect. In thisparticular instance, it is obvious that the arrangement of the tworing-like heater elements 12 and 14 with their opposed flow ofcombustible fluid will produce two concentric circles or rings of flame,thus giving a more wide spread area of flame and a more intense flamefor a given over-all vertical height of the apparatus.

It will be readily understood that although the two two heating elementshave been shown and illustrated as being vertically spaced with respectto each other, they may be positioned in other than the horizontalplane, while still retaining the basic principle of opposing streams ofcombustible fluid which mingle with each other and divide to produce apair of combustion rings.

Further, although the lower ring 14 has been shown supported by the legs18, it is obvious that the device may be mounted in any desired manneras in a stove, oven or the like.

As illustrated in FIGURE 3, it is also possible to still furtherincrease the output of heat from the device, by causing the upper andlower heating rings or elements 12 and 14 to be provided with upwardlyand/ or downwardly directed discharge nozzles 36 and 38 respectively. Inthis particular form, there will thus be provided four distinct heatingzones. There will be as mentioned in connection with the above ofFIGURES 1 and 2, an inner and outer ring of combustion generated by thenozzles 20 and 22. In addition, there will be an upwardly positionedadditional ring of combustion from the nozzles 36 and/or a downwardlydirected ring of combustion from the nozzles 38.

Further, a set of the nozzles 20, 22, 36 and 38 are disposed in verticalalignment with each other, and may be relatively staggered in anydesired manner.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly all suitable modifications and equivalentsmay be resorted to, falling within the scope of the invention asclaimed.

What is claimed as new is as follows:

1. A gas heating device comprising vertically alined and spacedring-shaped burners, means for rigidly supporting and connecting saidburners in rigid relation and in horizontal planes, burner nozzlesprojecting from the opposed horizontal faces of said burners in verticalalinement with each other for producing vertical streams of acombustible mixture impinging upon each other between the upper andlower burners whereby to effect an annular zone of combustion gasesbetween said burners and extending horizontally both within and withoutthe burners, means supplying a combustible mixture to each of saidburners.

2. The combination of claim 1 wherein said support means comprisesmembers mounted upon the top surface of the lower burner and engagingand supporting the lower surface of the upper burner.
